Agilent / Keysight 8671A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8671A. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 8671A faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.

This Agilent / Keysight 8671A is listed at $603.7. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
Agilent / Keysight 8671A calibration cost
NIST-traceable calibration for the Agilent / Keysight 8671A is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. Turnaround is 1 to 3 business days after receipt. See full calibration details →
